After replacement, how do you reset the throttle body?
Make sure the Throttle Position Sensor is the source of your issue before taking any action. You can reset the throttle position in your car once you’ve determined that it is.
TPS reset tools and equipment
All you will need to reset the throttle position sensor is a timer, such as a watch or stopwatch, and to be in the driver’s seat of your automobile.
Step 4Press the gas pedal down and fully release
You should repeat the next steps three times. Start by gradually depressing the gas pedal. When the pedal reaches the floor, hold it there for another three seconds or so. This should take about four seconds.
Similarly, if you depress the accelerator pedal, you should release it gradually, taking four seconds again. Three times through this method.
Step 5Switch the key to the off position
After completing step 4’s procedure, you should turn the ignition switch to the “off” position and remove the key for approximately 10 seconds.
The operation is successful if your idle is still. If it isn’t, you might have to go through steps 3 and 4 again, turning the ignition key until it is stable.
Alternately, you can try disconnecting your battery’s negative cable for around five minutes in order to reprogram your throttle position sensor. The fuse from your engine control module can also be taken out.
What happens if the throttle body is not reset?
Your engine will run lean if the TPS tricks your ECM into believing the throttle is closed when it isn’t. This will result in less fuel being injected to the air/fuel mixture. The engine won’t produce as much power as it should if there isn’t enough fuel in the mixture.
You’ll probably become aware of it the most when attempting to speed when this occurs. At first, your car might accelerate normally, but when you change into higher gears or move up in the rev range, you’ll discover that after a while, your automobile will flat-out refuse to accelerate any further.
The same thing may also occur in the reverse scenario, where the TPS instructs the ECM to supply too much fuel rather than not enough. In this scenario, your automobile will also use more gas than usual, and you can have a persistent gas smell when driving it, whereas there wasn’t one before.
Car Jerks and Accelerates Unintentionally
On rare occasions, the TPS may malfunction in a way that causes it to intermittently relay signals back to the ECM. The ECM will then change the air/fuel mixture as necessary because it will believe that the throttle is constantly opening and closing in this situation.
This may cause your car to jerk violently while you’re driving, and you might even experience momentary acceleration even while you’re not attempting it.
Rough Idle
The TPS is one of the components that enables your engine to maintain a proper idle speed when the gas pedal is not depressed and the engine is idling. However, if the TPS is broken or out of calibration, it will mess with the amount of gasoline coming to the engine and make it idle poorly.
An engine’s idle RPM should ideally remain fairly constant, but one with a poor TPS will alternate between slowing down and accelerating up.
Do throttle bodies require programming?
Does your new throttle body require a reprogram if it is brand new? A new throttle body must be reprogrammed to match the engine it will be used with in order to function correctly. This is because the engine’s air intake is controlled by the throttle body, and the engine won’t function properly without the right programming.
Some modern throttle bodies need to be reprogrammed when they are replaced because the engine computer frequently controls them. Other throttle bodies lack electronics and are purely mechanical.
How much does it cost to retrain a throttle body?
Depending on the automobile model and labor expenses, the cost to replace a throttle body ranges from $250 to $650 on average. The price of the throttle body ranged from $200 to $500, while the price of labor was between $50 and $150.
Depending on the manufacturer, model, and type of car, the price of the throttle body may vary. In essence, the cost of the replacement parts is the principal expense associated with changing a throttle body.
The sections of the throttle body can be successfully extended by routine maintenance, so you might not need a replacement for a very long time.
Depending on the car shop you choose for the replacement, the labor costs required can be cheap or expensive.
Keep in mind that after replacing the throttle body valve with a diagnostic scanner, you need to recalculate the throttle body valve.
Does the computer need to be reset after the throttle position sensor is replaced?
I’m here. If your engine’s throttle body has to be replaced and there was a pending code, the code will be cleared. The ECM (computer) would require a hard reset if the code was a permanent hard code. After around 13 minutes, unplug the negative battery cable (-), then reconnect it and make sure it is tight. As it enters a learn cycle, the engine light will turn off and all codes will be cleared. Unless it is causing several sensors to activate codes, the check engine light will stay off if the issue has been resolved, but if it has not, it will turn back on after 10 starts or three days of driving. Seek out a specialist, like one from Your Mechanic, if you require more help in resetting the ECM.
How Often Should I Change My Throttle Position Sensor?
Only if it tests poorly should your throttle position sensor be replaced. However, it’s recommended to take your car to a mechanic to get it looked at if you detect any problems with how it’s performing.
Does a Throttle Position Sensor Need to Be Calibrated?
Yes, if a throttle position sensor is replaced, calibration is required. Normally, you can get this done at a mechanic, but if you have the necessary tools, you might be able to do it yourself.
What Are the Symptoms of a Bad Throttle Position Sensor?
You can have problems with your vehicle’s performance, such as decreased fuel efficiency or power, if your throttle position sensor is malfunctioning. Your check engine light may also be on, which you may have seen.
How Do I Reset My Throttle Position Sensor?
Reconnecting the battery after a short time will allow you to reset your throttle position sensor. This will erase any stored computer codes and enable the sensor to reacquire its idle position.
Can a TPS Sensor Cause No Start?
Yes, a TPS sensor can prevent your car from starting. This is because the engine won’t start if the sensor’s reading is incorrect because it tells the computer how much air is entering the engine.
What Happens If You Unplug the Throttle Sensor Position?
If the throttle position sensor is malfunctioning, unplugging it will restore normal acceleration and idle for your car. The sensor is required so that the computer can accurately determine how much air is entering the engine and change the fuel mixture as necessary.
How Much Does It Cost to Replace a Throttle Position Sensor?
Depending on the make and model of your car, the cost of replacing a throttle position sensor can change. However, it usually ranges between $110 and $200.
Does the throttle body sensor need to be reprogrammed?
Your throttle position sensor may operate intermittently or inaccurately due to code issues. If not, you will require specialized software to reprogramme your sensor. A qualified mechanic should handle this task. If your sensor is just in need of repair, the issue may be with the wiring.
How do I change my electronic throttle control’s idle?
As automobiles age, the idle performance often changes, but fortunately, the adjustment is not too difficult. Finding and rotating the screw on the throttle body will change the idle RPM.
The following steps will show you how to change the idle RPM:
- From the air filter to the throttle body, follow the air intake hose. Look for a screw on the throttle body (possibly covered by a plastic cap). If the plastic top is still attached, pry it off.
- Reconnect the electrical connection to the idle air adjustment valves once the idle has been changed to aim for 650 RPM. Turn off your car and lower the hood.
- Open the hood, turn on your car, and let it warm up completely. While the automobile is moving, you will make this change. Be careful not to touch any hot engine components.
- Locate the electronic connector holding the idle air adjustment valve to the throttle body and detach it.
- To modify the idling, turn the idle screw.
- To raise RPM, spin the screw to the left; to decrease RPM, turn the screw to the right.

How is a throttle body recalibrated?
Turn the ignition switch “ON and wait for at least two seconds, then turn it “OFF and wait for at least ten. Turn the ignition switch “ON and wait for at least two seconds, then turn it “OFF and wait for at least ten.
Does the calibration of a throttle position sensor need to be done?
After installing a throttle position sensor, or TPS, you must calibrate it using MEITE.
Make sure the throttle sensor signal input is appropriately plugged and set to “TPS Raw” in the Analog Settings. As you adjust the throttle from fully closed to fully open, the signal on the selected pin should change from roughly zero to five volts. For instructions on how to connect it to the ME line of wire-in ECUs, refer to the Throttle Sensor wiring section. It will be correctly connected and assigned by the Plug-Ins in the base-map that is provided.
How can I calibrate the position sensor for my accelerator?
The ignition switch must be turned to the ON position before depressing the accelerator pedal fully and slowly from idle to full throttle in order to calibrate the accelerator pedal assembly. Three times through the process.
